As I said in the other thread though, if you're interested in metal (at least, heavy metal, the kind you normally associate with metal (ie. Slayer), rather than say doom, drone or some folk metal, which often sound completely different) the first album you should check out should be Powerslave by Iron Maiden, certainly not anything by Slayer for instance (which I can see being a bit more of an acquired taste). Powerslave is the heavy metal metal album.
Aces High
So, in conclusion, listen to this song. If you don't like it, I don't think metal (normal heavy metal anyway) is your thing. Nothing wrong with that.
